Overview

The CS5501 and CS5503 are CMOS A/D converters ideal for measuring low-frequency signals representing physical, chemical, and biological processes. They uti-lize charge-balance techniques to achieve 16-bit (CS5501) and 20-bit(CS5503) performance with up to 4 kSps word rates.The converters continuously sample at a rate set by the user in the form of either a CMOS clock or a crystal. On-chip digital filtering processes the data and updates the output register at up to a 4 kSps rate. The converters' low-pass,6-pole Gaussian response filter is designed to al-low corner frequency settings from 0.1 Hz to 10 Hz in the CS5501 and 0.5 Hz to 10 Hz in the CS5503. Thus, each converter rejects 50 Hz and 60 Hz line frequencies as well as any noise at spurious frequencies.The CS5501 and CS5503 incdude on-chip self-calibra-tion circuitry which can be initiated at any time or temperature to insure offset and full-scale errors of typi cally less than 1/2 LSB for the CS5501 and less than4LSB for the CS5503. The devices can also be applied in system calibration schemes to null ofset and gain er-rors in the input channel.Each device's serial port offers two general purpose modes of operation for direct interface to shift registers or synchronous serial ports of industry-standard micro-controllers. In addition, the CS5501's serial port offers a third, UART-compatible mode of asynchronous communication.
